It was a stupid point. It's for the sake of better reflecting our society. Superheroes are escapist fare meant to represent the human ideal, fighting off the "bad guys" and striving to do what's right. A really bizarre metaphor for our system of ethics, characters for our kids to look up to identify with.

It's hard to pretend it's truly all-inclusive entertainment when it's a bunch of straight white dudes hanging out and saving the day.
